Know Your Numbers
Most Americans don't understand health care. Here's what you need to do to make sure you're not one of them.88% of Americans don’t understand basic health information. That’s the finding from an American Heart Association study released in June that shows most Americans don’t know what bad blood pressure numbers are, the causes of diabetes, and some didn’t understand the results of a basic health test. As a nation, our limited health literacy is preventing us from identifying the symptoms and warning signs of cardiovascular disease as well as the treatments and lifestyle steps needed to prevent it.
Dr. Jeffrey Uzzilia a board certified cardiologist at Capital Cardiology Associates has a special interest in coronary artery disease treatment and prevention, as well as congestive heart failure. As a specialist in heart health, he sees the confusion patients have with health information. “I can understand why people don’t have a great grasp on their blood pressure numbers,” says Uzzilia. “There has been a lot of confusion over the new blood pressure guidelines, the most recent numbers that were published last year were quite different from the guidelines that were published in the past five years. Five years ago the guidelines suggested that blood pressure could be less that 140 over 90. Within five years the new guidelines say that 120 over 80 would be the ideal number. I think it’s confusing for people.”

The scientific statement published in the American Heart Association’s journal Circulation reported that more than half of people with low health literacy did not recognize an abnormal blood pressure reading are less likely to get it under control. As Uzzilia asserts, “It’s our responsibility as medical providers to explain why there are differences, why the guidelines are important, but why there may be reasons why we disagree with the guidelines.” Why would a physician disagree with blood pressure guidelines? “The model from several years ago I disagreed with and I prefer the new numbers where they acknowledge that maybe the blood pressure is not as high but lowering it does have some benefits particularly in women who are at higher risk for stroke even with minor elevations in their blood pressure.”

The reason for changing the numbers
The goal of the change is to help people take steps to control their blood pressure earlier to reduce hypertension, a major risk factor for heart disease and stroke. Last year, the American Heart Association with the American College of Cardiology redefined high blood pressure for the first time in 14 years. “The new guidelines for normal or healthy blood pressure is 120 for the systolic and 80 for the diastolic,” reported Uzzilia. The new guidelines eliminate the category of prehypertension, which was used for blood pressures between 120-139 over 80-89. People with those readings now will be categorized as having either Elevated (120-129 and less than 80) or Stage I hypertension (130-139 or 80-89). As a result of these changes, half of the adult population (46% of US adults) will have high blood pressure, or hypertension. Most impacted are men and women under the age of 45 who will consulted by their doctor on healthy lifestyle changes.
Dangers of high blood pressure
The American Heart Association warns that high blood pressure accounts for the second largest number of preventable heart disease and stroke deaths, second only to smoking. It’s known as the “silent killer” because often there are no symptoms, despite its role in significantly increasing the risk for heart disease and stroke. High blood pressure is a common disease. You have a higher risk for this disease if you are overweight. Your risk is higher if you eat a diet high in salt, if you drink a lot of alcohol or if you don’t exercise enough. Your risk gets higher as you get older. This disease is more common in men and in African Americans. Plus, you have a higher risk if you have a family history of this disease.
It’s important that you have regular visits with your doctor and understand your blood pressure numbers so that your doctor can work with you on a plan to manage your condition. Treatment options often include a healthier lifestyle (free of smoking, alcohol, with more exercise, and a heart healthy diet) and medications. If left untreated, high blood pressure becomes severe and can lead to sever complications even heart attack, stroke, an aneurysm, kidney problems, and vision loss.

What your numbers mean and why they matter
Blood pressure is measured with two numbers written like a fraction. The top number is the pressure in your arteries when your heart is pushing out blood. The bottom number is the pressure between beats, when your heart is resting. The higher the pressure, the greater your risk for health problems. As Dr. Uzzilia discussed, that is where the confusion begins. “There’s a lot of misinformation about your blood pressure numbers. I’ve had patients tell me that, ‘all that matters is the lower number,’ or the diastolic pressure. Or that, ‘only the top,’ or the systolic number matters. In fact, they are both very important. The systolic number is the peak number or the high number when blood is ejected out in the arterial circulation from the heart. The diastolic blood pressure is the lower number after the heart has already pumped the residual pressure in between the heartbeats.”
Overall, knowing your numbers and having healthy blood pressure will lead to a lower risk of stroke, cardiovascular disease, and kidney failure. Know your numbers by seeing your doctor for a yearly visit. Also incorporate a heart-healthy diet that reduces salt and incorporates potassium-rich foods such as bananas, potatoes, avocados and dark leafy vegetables. If you are an adult over 40, ask your doctor for suggestions on weight loss, quitting cigarette smoking, cutting back on alcohol and increasing physical activity.
